ABSTRACT
The anatomical relationship between the recurrent laryngeal nerve (RLN) and the inferior thyroid artery (ITA) was studied in 76 embalmed corpses, 8 females and 68 males. In both sexes, the RLN lay more frequently between branches of the ITA.; it was found in this position in 47.3 percent of male corpses and 42.8 percent of female ones. On the right, RLN was found between branches of the ITA in 49.3 percent of the cases, anterior to it in 38.04 percent, and posterior in 11.26 percent. On the left, the RLN lay between branches of the ITA in 44.45 percent, posterior to the ITA in 37.05 percent, and anterior to it in 18.05 percent of the cases. In 62.68 percent of the cases, the relationship found on one side did not occur again on the opposite side. There was a significant difference (p<0.05) in the distribution of the 3 types of relationships between the RLN and the ITA, on the right and on the left. Racial variations could contribute to an explanation of the differences observed by authors of different countries in the relationship between the RLN and the ITA
